The object of my invention is to provide a novel and useful attachment for cotton gins for the purpose of separating sticks, stones and other foreign matter from the cotton.

I attain these and other objects of my invention by the device illustrated in the accompanying drawings, in which,-

Figure 1 is a vertical section through my invention, partly in side elevation;

Fig. 2 is a section on line 2--2 of Fig. 1 and Fig. 3 is a vertical section on line 3 8 of Fig. 1.

Like numerals designate like parts in each of the drawings.

Referring to the drawings, I provide an intake chute 1 and an exit chute 2 having a connecting chamber 4 in which is mounted a corrugated sheet or baffle 5 which in addition to its corrugations is provided with spikes 20 6. The baffle 5 is suspended from a transverse rod 7 which is detachably secured by the removable bearings 8, as shown in Fig. 1, which members are bolted on the respective chutes 1 and 2 and are removable.

The rod 7 is bent at right angles at one side of the machine to form the balancing rod portion 9 which carries a weight 10 adjustably secured on the rod by the set screw 11. The bottom of the intake chute l is provided with a pocket 15 and the bottom of the exit chute is provided with a similar pocket 16 the bottoms of these pockets being preferably removable. I also provide a projecting strip 12, as shown in Fig. l, and directly beneath this strip extending beyond the same I provide a slanting wall 13 on which the foreign matter or heavy material which strikes the baille plate will flow and thence flow downwardly and out through ,the discharge chute 19. One side of the discharge opening is provided with a slanting wall 14 which extends upwardly to the bottom of the inner lower end of the exhaust chute 2, as shown in Fig. 1. I may provide any suitable suction for f sucking a current of air through the device and have illustrated a conventional motor 17 and conventional fan 18 for the purpose.

The operation of the device is indicated by the arrows in Fig. 1 of the drawings. The lighter material passes under the baffle and -means .foradjustin'g-the position-of the baffle plate.
